The appliance garage on the right houses the Alpenrost. I had them put a direct vent into the wall to get rid of the smoke. I'm sure it will require explanation if we ever sell the place....

I run the Alpenrost with the door all the way closed and the fan on. At first I left the door open a crack but the fan pulls so much air through, it didn't even finish roasting in 20 minutes. I had to start a new cycle. Here's a closer shot:

The Pavoni is the machine I used for the last 10 years. I bought it used at a garage sale for $15 and fixed it up for another $70 (old gaskets and a blown thermal fuse). It's been great but the temperature control was really terrible compared to the S1. I actually had to run the portafilter under cold water between shots to keep the espresso from boiling out of the bottom. It's tough at this altitude because water boils at 92.4 C (198F). Fortunately the S1 solves this.
Here's a shot of the S1:

I keep the syrups mostly for guests and the kids. The grinders are Isomac Gran Macininos, but I'm thinking of getting a Mazzer Mini-E. The steps are too large on the Gran Macinino (10 seconds sometimes in one click).
In case you're worried the kids aren't drinking coffee.... They like a steamed milk with powdered chocolate and vanilla syrup.
